Acid -proof Cement Mortar

Acid -proof Cement Mortar

Acid -proof Cement Mortar

(OP)
Hello all,

I'm a structural engineer working on a remediation project.  The original plans show steel tanks lined with a "Duro-San" membrane and then faced with two vertical courses of acid proof brick.  The tanks were used for cleaning equipment and parts. The brick mortar is listed as "Lecite" cement and the adhesive used to fix the brick to the membrane and the membrane to the steel tank is listed as "Brimsto" cement.

Does anyone have any knowledge of those products listed in quotes above.  Any info would be appreciated.

PS: I also posted this in the "concrete admixture" section of Eng-Tips but thought this section may be more appropriate.

Thanks.

Don't know about Lecite but we used Furane based compound extensively, in one of my previous companies. Do you mean Brimstone cement for the second one? If so, it is a sulphur based cement.

Thanks quark for the reply.  

The original plans were dated in the early 1950s. I thought the original designer may have been referring to brimstone cement as well but I found the "Brimsto" reference on several plan sheets and in several locations on each sheet.  If it is a typographical error, at least the draftsman was very consistent.

RE: Acid -proof Cement Mortar

Not much help but a little information.

In the 50's we used sulphur cement on all our acid brick. We used acid brick for flooring and ditch lining along with lining our pickling tanks.
There were some variations of sulphur cement used for bonding on brick walls.
In some cases asphalt + creosote was used to bond acid brick, especially in walls.
Another material used to bond brick acid brick was albumin, egg whites.
The material for membranes was quite restricted in the 50's and I can't remember any membrane material that could be bonded to the brick. The rubber membranes were usually attached to the tank walls with rubber cement.

If you are looking for current information on Acid resistant brick systems try Steuler or Nori acid bricks.
